' SEGTIONAL Application filed April 21,

This invention relates to heat into"- changcrs and more particularly to an improved form of sectional radiator for in ternal combustion engines.

The main oljects of this invention are to provide in a sectional radiator, 'animproved form of oint between the headers and their companion tanks; and to provide an improved arrangement of con'ununicating means between the SGJCI'Dil. headers and the upper andlowcr. tanks, which arrangement is adapted to permit a freer flow of the cooling medium between the headers.v

In prior-forms of sectional radiator construction, the several core unitshave each been provided with upper and lower headers, which. headers have stepped scarf joints for coacting with a similar stepped scarf joint of the upper and lower tank. Each header has also'been provided with a port througl' its stepped scar'f joint registering'with a port in the coacting stepped scarf joint of its companion tank. Because of thenarrow width of such stepped scari joints, it has been impossible to provide a port whose orifice is of suiiicient width to permita free flow of the cooling medium between the tanksand their communicating headers; moreover, the flow of the cooling medium between the tanksand the headers is further restricted by virtue of the fact that the current of the cooling medium is forced to flow in a more or less tortuous path.

In the. present invention, the upper and. lower headers each have a comparatively wide angularly disposedshoulder and each shoulderis provided with a port. The top and bottom tanks each have an angularly disposed shoulder coacting with the angularly disposed shoulders of the several headers. The angularly disposed shoulder of each tank is provided witha plurality of ports registering with the ports of the companion headers. Because of the comparatively wide angularly disposed shoulder of the top and bottom tanks and the width oi the coacting shoulders of theseveral headers, it is possible to provide ports having orifices of greater width, thereby providing a freer flow of the cooling medium between the tanks and headers of the several core units. Moreover, the disposition of the coacting angularly disposed shoulders is such that the current of flow between the tanks and the headers of the several core units is more direct and less tortuous than the current of the cooling meeArE r Fries.

dium in radiators having scarfj oint connections. 1 a y .Aniillustrative embodiment of the invenion is shown in the accompanying drawings wherein: V

Fig.1 is a fragmentary front elevation of a sectional radiator for internal combustion engines, a, portion tiereot being broken away.

Fig. 2 1s an end view thereof taken on line 22 of Fig. 1.

.Fig' 3 is a fragmentary sectional view thereof taken on line 3-3 of Fig. 2.- c

In the drawings the radiator has the usual upper tankland the lower tankfl secured together by the vertically disposed side supporting frame members The upper tank is provided with the usual threaded filler neck a on which a closure cap 5 is screwed. I I A series of elongated vertically disposed core units 6 are provided and each unit com: prises a plurality of vertically disposed water tubes 8 which communicate with upper and lower headers 9 and 9 respectively. The

.core' sections are provided with a plurality of horizontally disposed radiating fins 7. Each of the several headers 9 and 9 have an angular-1y disposed shoulder 10 inclined relatively to the horizontal and each shoulder is provided with a rectangular port 11. The top and bottom tanks 1 and 2 each have a similarly disposed shoulder 12 coacting with I the inclined shoulders of its companion headers and each shoulder 12 is provided with a plurality of rectangular ports 13 registering with their companion header ports 11.

' Means for securing each otthe several headers with their upper and lower tanks comprises bolts '14 which pass through integrally formed tubular members 16 of the headers and tanks andat an angle approximately the transverse of the angle of the coacting shoulders.

The transaqueous passageways furnished by the diagonal. tubes 16 dry-house the bolts 14, and so protect them against rust and consequcnt weakenin z The arrows in Fig. 2 indicate the flow of the coolingmed'ium from the inlet through the upper hose connection into the top tank and throughthe registering communicating ports 11 and 13 into the upper headers 9,

thence downwardly through the vertically.

disposed water tubes to the lower headers 9 through the registering communicating ports of the lower headers and the bottom tank,

' lower hose conn *ction 17.

it will thus be seen that theimproved form panion tanks so arranged that the flow of the cooling medium from the headers to the tan LS is less restricted because possible to provide ports of greater size.

l'Vhi-l'e but one specific embodiment this invention has be :1 shown and described, it will be understood that numerous details of the construction shown may he altered or omitted without departing from the spirit of. this invention as defined by the following claims:

I claim:

1. A radiator of the class described comprising an upper tank, a lower tank i. spaced relation to said upper tank, a core unit for providing communication between said tanks, coacting inclined shoulders on said tanks and unit, said shoulders having registering ports therein, and'holts extending through said unit and tanks disposed transversely to said inclined shoulders for securing said unit to said tanks, the latter having inclined'fiuid-tight transaqueous passageways extending to an elevated position in the back to accommodate said bolts with dry housin 2. A sectional radiator of the class descrihedcomprising an upper tank, a lower tank in spaced relation to said upper tank,

a series of core units forproviding conununicationhetwecn said tanks, a to p' and a bottom hear or on the top. and bottom ends of said units respectively, the under side of said upaer tank having a horizontal surface and u upwardly inclined surface providing a aheulder, aid inclinec surface having ports d bottom tank having a horizontal ,per ice and a downwardly inclined suriace providing inclined shoulder, said inclined shoulder having ports therein, said sectional u top and bottom headers having surfaces which conform to said upper and lower tank surfaces respectively and having ports therein which register with the ports eir respective upper and lower tanks, and

in .11: a plurality of bolts, one at each edge of each header, and passing through the upper head ers and upper tan; and through the lower headers and lower tank for securing said sec-- tional Y to said upper and lower tanks, said hell.) being disposed transversely to the inclined shoulders on said upper and lower tan and headers, said tanks having transa, ous tubular passageways to dry-house colts, wi h passageways are horizontal- C ly nattened to accommodate each a pair of s i. its.
